Ben Garner was pleased his side kept playing football as the Addicks came from behind to advance to the Fourth Round of the Carabao Cup.
Supersub Chuks Aneke equalised four minutes from time as the Addicks drew 1-1 at Stevenage before Scott Fraser scored the winning penalty to send Charlton through.
Garner said: “It was a tough game. A really tough game. It’s a difficult place to come. Stevenage are really good at what they do. I was really pleased with how we kept pushing, second-half. It’s hard to break that down. We created a couple of good opportunities, especially off set-pieces.
“It was fantastic to see Chuks get the goal. Then we’re pushing to try and get the winner and we did it on penalties.”
Charlton won the shootout 5-4 with Joe Wollacott saving from Jake Taylor before Fraser's calm finisher.
“The standard of penalties was absolutely brilliant,” said Garner. “I don’t remember seeing five better than that in a penalty shootout. It is a great save from Jojo to top it all off.
“A lot of the lads practice penalties all the time. You go into a shootout thinking ‘are they going to do what they normally do?’, and they did. They showed great composure, great confidence and really good technique.”
The win means the Addicks will be in Thursday’s Fourth Round draw and Garner was asked what draw he was hoping for.
He said: “As big as possible. We’ll take what we get. But I’d love to give those supporters a huge tie against a Premier League side, either home or away. We spoke about that before the game – make sure that when that draw is happening on Thursday that we’re there and got a chance of drawing a big tie.
“As big a team as possible or a local derby that is an exciting one for the fans. We’ll see who it is and prepare in great detail to try and win the game.”
